Title: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on October 21, 2016, 10:12:35 AM
Hey,

 I've here a cool little project that was developed by mrdo, member of the German ArcadeZone Forum. He put together a PCB that supports Jamma Interface for the Raspberry PI.

(https://lh3.googleusercontent.com/-ZWXym3kYi2E/V-y9j9qXIHI/AAAAAAAATrE/zG3HilzUabg/s400/1474657763916.jpg)

Just put the RPI3 under the PCB, plug the audio cable, attach sd card  and throw it into your cab - done.  8)

It has native 15Khz RGB support, direct lagless controls, Jamma Interface and 6 Buttons support.

There is NO need of USB Encoders, HDMI and VGA converter or Jamma Harness modification.

Youtube Video https://www.youtube.com/watch?v=9qn33UmuMVU

We spilt work - mrdo is delveloping the hardware and cares about the software. Pi2Jamma comes with an own image.

I`m in charge of manufacturing and production.

Pi2Jamma can be pre order here

http://arcadeforge.net/PiJamma/Pi2Jamma::248.html

Current State :

- Image is in work. Simple Version works. This work will never finish I guess ;)
- PCB is ordered and currrently at customs.
- All parts are ordered and to 90'% deliviered.

Cheers bencao

I notice scan lines missing in Metal Slug....no native resolution in arcade monitor?


Title: Re: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on October 21, 2016, 12:16:56 PM
Sure, different resolutions can be driven by the Raspberry Pi by changing the modelines.

Post by: slowcade on October 21, 2016, 09:43:24 PM
Looks nice! Can I cut the power to the cab instantly like with most jamma games, or do I need to do a "safe shutdown" procedure in some way to prevent corrupting the sd card?


Title: Re: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on October 22, 2016, 08:09:56 AM
We plan to implement an image with reduced write access. If someone experience fs errors due to switching on /off then the image can be run from usb.

Sounds very good!  :)

Post by: Ianski on October 22, 2016, 03:37:49 PM
That looks awesome I'm very tempted to order one soon.
Does it take power from the edge connector or is a separate supply needed?

Also how do you connect the controls?

Thanks.


Title: Re: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on October 22, 2016, 04:11:04 PM
There is no modification needed in the cab,  no extra psu. Power will be taken from the Jamma interface.

Controls will be forwarded from Jamma interface as well and forwarded to the gpio.

and the next 10 pcs.  8)

Some more info:

- Video is amp is on board
- np USB encoding. GPIO takes controls directly
- no modification must be done on the cab. Take your Jamma Harness as it is. This is important if you want to continue using your cab with Arcade PCBs.

Post by: bencao74 on December 12, 2016, 01:16:34 PM
some updates.

first batch is sold, 2nd is on the way.

Some guys made very nice Graphical Menus für the Pi2jamma.

We made progress on the so called pixel perfect resolutions. I general it was not possible to switch resoltuions without editing the config.txt and make a reboot.

We have now made a dynamic resolution switcher. It works on the basis of a resolution table for each games. When the game is selected the according resoolution will be sest and the game started.

The resoltion table was generated from the roms itself. But sure, the resolutions can be modified in that table to meet specific CRT model and such.

Other stuff is integration of more fs types to support more windows made usb sticks, C64 emulator can be started from shell, to play barbarian, chopping of some heads....

...just unpacked my order I got months ago (:oops:)
...and realized it's just the PiJamma interface, but not with the Raspberry to plug on it. ( :oops: bis)
So what Raspberry model should I order? Can I order one 'ready to go' with the Pi2Jamma ? I mean with the front end + games with it ?
Thx.

Received my board.
Downloaded image and put roms on USB,
Works great.
Here is old Jamma cab playing Shinobi (I know i need to fix that joystick and finish button replacement)

Just need to tweak to get some settings working.
I know how to change Keyboard and Wifi but says i dont have permission to change with user "x" ?

Will test on my Sega Astro City in my workplace later in the week.

looks great. :)) I like the centipede artwork :))

for editing files with root rights you need to login as root.

type su
pass root

then you are allowed to edit files you questioned.

Alternative : use console image, goto "options"-"command shell"

Cheers

Ah easy, sorry thought the default user was "x" and password was "y".

I will have no problems with keyboard and wifi then.

It is a big dark though, i dont need to increase brightness on other boards,
Any ideas?

After months (year?) of that stuff still packed (  :oops: ), I've finally found time to test THE ultimate setup for me, which is :

Raspberry 3 -> Pi2Jamma + Pi2Scart  :arrow:

(http://www.arcadelifestyle.net/forforum4/pi2jamma1.jpg)

(http://www.arcadelifestyle.net/forforum4/pi2jamma2.jpg)

I was afraid to spend hours and hours doc reading to make all that stuff working... and ... finally NOT AT ALL. It's as easy as your ABC!

The result is just awesome! Full 15khz RGB / 60 Hz / 1:1 ratio pixel perfect
I've used few games who have perfectly smooth scrolling to test  ...

(http://www.arcadelifestyle.net/forforum4/pi2jamma4.jpg)

(http://www.arcadelifestyle.net/forforum4/pi2jamma3.jpg)

It's so smoothhhhhh  :-* Pictures don't do justice... display looks amazing! And the emulation is reallllly good!  :-*
I'll definitively use this setup to replace old computer or these crappy x in one chinese boards!

Thank Jochen for providing me the Pi2Scart adapter, which does a fantastic job (picture is brighter with it).

On the negative side, I had several time this bug, while browsing fast the games available on the USB stick :

(http://www.arcadelifestyle.net/forforum4/pi2jamma5.jpg)

Any idea what is the problem?

Oh, and I can't remove the front end music (can't find anything related to the sound in the option menu?). How to remove it ?

Finally will it be possible to configure the software to load one game only and disable the escape button?

Thx again for this amazing product!  :-* :-* :-*

I have some (maybe stupid) questions about this.
I want to run Sente's Off The Wall in a dedicated cabinet.
The original board set is quite expensive and hard to find. It's a two player game which uses two joysticks and two spinners.
Can I boot directly to the game, and can I use the x and y axis from a usb mouse (the type with a ball inside) to connect two spinners to the Pi?

Thanks for your review and sorry for the late reply.

Issue 1 : software expects the pi2jamma  joystick. Just turn on the pi2scart mode to turn off the pi2jamma joystick in the software.

Issue 2 : the music is placed on the usb stick in folder menu-audio. Replace or delete this files. New version has additionally the features toggle music on / off and set volume.

Issue 3 : option - lock game or unlock game for disabling or enabling escape from game.

Hope this helps.

Hello All,

After recently learning about the Pi2JAMMA, I ordered mine yesterday and joined this forum today. (I can't wait for the board to arrive)

My intent is to use the Retropie image on it (specifically the 'already-prepared' v0.8.1 image on strike-devices.net).

I do have a question on that image - is it also configured to try to find ROMS on a USB stick, or is this configured like the 'regular' Retropie at ~/RetroPie/roms/?



Title: Re: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on February 15, 2018, 10:22:35 PM
Hey,

 its regular with roms on card.

Cheers

Hey,

Cheers

Brilliant, thank you.

And then a second question - is my assumption correct that pins 25/26 and c/d are being used for Player 1 Button 4/5 and Player 2 Button 4/5 respectively? (rather than N.C. as per the 'classic' JAMMA spec)



Title: Re: Pi2Jamma : Raspberry Pi Jamma Interface with 15khz RGB
Post by: bencao74 on February 15, 2018, 11:36:48 PM
Correct

B6 is wired via extra screw terminals.

Post by: olafwagner on July 29, 2018, 04:29:24 AM
I finally got my Pi2JAMMA installed today (took a few months to sort out some other things).

I installed the Pi2JAMMA RetroPie image (I still had the retropie-4.3-pi2jamma-0_8_1.rar image) and am facing a few small challenges with the software:

- The Emulation Station menu seems to work well (at what I guess is 240p on my arcade monitor?) but when I launch any arcade game (I am using lr-mame-2003) it seems like the X-axis is scaled about 4x and the y-axis is scaled approx 2x (I attached 2 screenshots below). I have been scratching around in the RetroArch settings, but doesn't seem to make a change.

- When I press Coin-1, I (correctly) get a keyboard '5', however, when I press Coin-2, I don't get '6'. I checked my JAMMA harness for continuity, and all seems good on pins '16' and 'T' respectively. Is there somewhere in the software that I can review the pinout mappings? (I assume this maps to the GPIO somehow)

- I assume (once I fix my scaling issue) that 2-players will work just fine in MAME through the 'keyboard-style' controller that Pi2JAMMA is using. However, how does one get this to work for other systems? (eg: NES) (I guess this is more a Retropie-specific question rather than Pi2JAMMA, but this is my only 'keyboard-only' Retropie setup :-)

Thanks.

Post by: olafwagner on August 13, 2018, 02:17:32 AM

I installed the 4.4 image from Strike-Devices and can report that all is working well. Both the video scaling and Coin2 work as expected on my JAMMA cab (with standard resolution horizontally mounted monitor)
